Exactly, the script is working only with foreign voices (changing your country voices is not allowed by the script).
After using the script to change a foreign Tomtom voice with one of your canned voices, it's flagged as a country voice.

I have two devices with GO 1.9 patched and work well.
But in both, I can't found content.db file.
Is it possible to no have content.db installed in device?
can you post content.db file to use it and add voice in my device please?

Hidden files names in Android are beginning with a dot ".".
So, "Content.db" is not a hidden file.

I'm using Samsung S4 (Android 4.4.2 with no root). And, I can find the "Android/data/com.tomtom.gplay.navapp" directory into my SDCard and also into my phone.

Could you give us the android version you have ?
If somebody with the same version could say if the "content.db" file exist on its phone ? If the test is done with a rooted phone, it will be also possible to do a search for the "Content.db" file all over the phone/SDCard directories.
